In a 40 breeder, only Cryptoheros nanolueus, and Herotilapia multispinossa.
In a 75, long tem Cryptoheros myrnae, sajica, honduran red points, H nicaraguense, and some Gymnogeophagus. Temporarily H carpintus, and grammodes, but as soon as the males hit about 7", the females were goners.
In 125s, Chuco intermedia, Nandopsis teracanthus, and a few others that max out at bout 10".
In 150 gals, and larger haitiensus, P managuense, motaguense, and some mid growth Vieja (like breidhori fenestratus, and zonates, but about the time they grew lager than 12" (sometimes earlier), dividers were needed to keep females secure.
In all of the cases above there were successful spawns, some were eventually saved by dividers, many I didn't catch in time, and one member of the pair were killed, and eggs or fry destryed.
in 75s and 125s many African, and Malagasy cichlids did fine (although some of the larger oneslike buttikoferi and large Paretroplus, even larger than 150 gal tanks weren't enough).
